SHUTTLE FDR wEAvINe nAIncLorH, &c.

Specification of Letters Patent No. 8,902, dated April 2'7, 1352..

Whole shuttle, showing the springs, and the bar, or alternate wedge,which works them, in their proper posltions for use. Flg. 2 1s aperspective view of a longitudinal section or binding wedge.

of the shuttle, showing the springs, when separate, or free, from thebar, or alternate, Fig. 3 is a perspective View of the bar, oralternate, or binding wedge, by the sliding of which the springs arepressed, or released.

I make the shuttle of hard wood, or any other suitable material, of theordinary size, and suit-able shape, (as shown at A, Fig. 1,) so that itmay be used by hand, in common looms, or by any of the various pickmotions of the power looms. V

I make a longitudinal slot through the whole thickness of the shuttle,(near one side,) nearly its whole length, as shown at B, Fig. 1, or forconvenience of repairing, or altering the spring, etc., it may be madein two parts, and the thin part, shown in Fig. 2, attached wit-h screws,or otherwise. In this slot, and. on the thin side, I attach two longflat springs, C, and D, Figs. 1, and 2, in such a posit-ion that theywill spring out from this thin side, as seen at C, Fig. 1,

and C, and D, Fig. 2, sufficiently to receive a hair, or other material,with an inclined plane at, or near, the outer end of each, as

seen at a, and Z), Figs. 1, and 2.

I insert a bar, 0, Figs. 1, and 3, also having inclined planes at eachend, the reverse of those on the springs, to work on the inclined planesof the springs, as seen in Fig. 1, so that it will act, alternately, asa wedge on the inclined plane of the springs; so that when the bar, 0,is forced, by any power, toward one end of the slot it will release thespring at that end, as seen at a, Fig. 1, and press the spring at theother end, as seen at b, Fig. 1, and vice versa; so that one end of theshuttle will .be,by means of the spring andwedge, firmly holding the endof a hair,

, as seen at (Z,.Fig. l, to draw it into the open warp, while the otherend will be open to receive another hair at the other side of the warp.I This bar, 0, is held in the shuttle by screws, or pins, passingthrough holes in the thin part c, and 6, Fig. 2, and through slots f,and f, Fig. 3, in the bar, into the body, A, of the shuttle.

To use the shuttle, the butt end of a hair is placed under one of thesprings, and the bar, or wedge, pushed toward the other end of theshuttle, when the inclined plane of the bar will press the springagainst the inside of the thin. part of the shuttle, and confine thehair, as seen at cl, 6, Fig. 1, while the other spring is relieved. Theshuttle is then thrown through the open warp, by hand, or otherwise,carrying with it the hair. As the shuttle passes into the shuttle box onthe opposite side, a stop strikes the end of the bar, 0, and forces ittoward the other end of the shuttle, which relieves the spring, 6, andtherefore drops the hair to be beat up by the reed, or batten. And. asthe shuttle arrives in the shuttle box, as before described, before thebar, or wedge, is moved, the butt end of another hair is fed under thespring, a, so that the sliding of the bar, 0, while it releases the hairwhich has been drawn through, also acts upon the spring, a,

and secures, or binds, the other hair, which is the bar coming incontact with another stop,

as before described; so that the alternate motion of the shuttle, bymeans of the stops,

slides the bar, by which means the hairs are alternately confined, to bedrawn through, and released, or dropped, when drawn through, ready to bebeat up. I

The hair may be fed by hand to the shuttle, or by any other convenientmethod; and the shuttle may be worked by hand, or any other suitablepower or machinery.

This shuttle is equally applicable to the weaving of grass, chip, cane,palm leaf, etc., which are woven without selvage, or where the woof doesnot return, but each crossing is a separate piece. It is also applicableto drawing in and out rods, as in weaving piled fabrics.

The advantages of my improvement consist in making the shuttle in suchshape that it may be conveniently used in the manner of a commonshuttle, (by hand or any other power,) and therefore, may be used withmuch greater rapidity. And, in having the springs and bar so arranged,that the same motion which releases one piece of the woof will bind thenext. And, in having the spring to receive the piece of woof, alwaysopen where the piece is to be fed.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination of the sliding bar, 0, with the springs, a,'and b, whenused in connection with stops attached to the shuttle boxes, (or otherconvenient fixtures,) so that the motion of the shuttle will slide thebar in is constructed, arranged, and combined, substantially, as hereindescribed.
